Program Frequency Speed Reference Setpoints

 

This parameter is used to set the gain and bias of the isolated V/I input terminal

 

when the V/I terminal is used as the control input while operating in the Speed

 

Control mode or the Torque Control mode.

 

This parameter sets the V/I input level that is associated with the V/I Input

 

Point 1 Frequency setting when operating in the Speed control mode or is

 

associated with the V/I Input Point 1 Rate setting when operating in the

 

Torque Control mode.

 

Note: See note on pg. 44 for more information on the V/I terminal.

Direct Access Number — F201

V/I Input Speed Control Setup

Frequency Settings

Perform the following setup to allow the system to receive Speed control input at the V/I input terminal:

• Set SW301 of the Terminal Board to Voltage or Current (see Figure 9 on pg. 24).

• Program Frequency V/I Settings V/I Voltage or Current input signal.

• Program Fundamental Standard Mode Selection Frequency Mode 1 V/I.

• Program Fundamental Standard Mode Selection Command Mode

Selection Terminal Block.

Speed Control

Perform the following setup to allow the system to perform Speed control from the V/I input terminal:

Set V/I Input Point 1 Frequency (F202).

Set V/I Input Point 1 Setting (F201) — the input analog signal level that corresponds to the frequency setting at V/I Input Point 1 Frequency.

Set V/I Input Point 2 Frequency (F204).

Set V/I Input Point 2 Setting (F203) — the input analog signal level that corresponds to the frequency setting at V/I Input Point 2 Frequency.

Provide a Run command (F and/or R).

Once set, as the V/I input voltage or current changes, the output frequency of the ASD will vary in accordance with the above settings.

This parameter value is entered as 0% to 100% of the V/I input signal range.

The V/I input is commonly used for a 4 – 20 mA current loop signal where

4 mA equals 20% of a 20 mA signal, set this parameter to 20% for 4 – 20 mA current loop signal applications.

Note: When using the isolated V/I input terminal the IICC terminal must be used as the return (negative) connection.
